It is not possible to renounce lust without performing authorised spiritual activities. Lord Krishna declares that that those who whimsically ignore or spitefully disregard the ordinances and injunctions prescribed in the Vedic scriptures expressly for the benefit of all beings and contrarily act frivolously impelled by the impulses of desire will achieve neither knowledge of truth, perfection nor moksa or liberation from material existence. Such offenders who ignorantly or purposely transgresses the eternal prohibitions of the Vedic scriptures will never be able to maintain any permanent happiness and tranquillity.

The word sastra refers exclusively to the Vedic scriptures. Vidhi means the injunctions and ordinances within them. The Vedic scriptures are the Supreme Lord Krishna's mandates. Whosoever foolishly abandons these instructions and utsrjya or transgresses the injunctions and ordinances to drift whimsically wherever their desires aimlessly take them will never achieve siddhi or perfection beyond mundane conceptions, never achieve sukham or happiness of any longevity or param gatim the supreme goal of human existence.

In order to conclusively establish the evidence and justification for abandoning all demoniac vices and evils by permanently avoiding lust, greed and anger which so forcefully takes one directly to hell; Lord Krishna irrevocably reveals the reason. Any jiva or embodied being in a physical body or subtle body, who whimsically ignores the ordinances of the Vedic scriptures or who foolishly disregards the injunctions of the Vedic scriptures and instead transgresses the prohibitions prescribed therein that are for the welfare and benefit of all creation; can never achieve any good for themselves or any good for others. Such foolish miscreants obstruct all possibilities for their own best interests and ostracize all their opportunities for spiritual advancement. Those who transgress the Vedic scriptures and are slaves to their senses, controlled by the base urges of the physical body, and who indiscriminately follow every desire of the mind; will never achieve perfection, happiness or the ultimate goal of existence even if one strives for that for millions of lifetimes. The use of the relative pronoun yah meaning he who symbolises the jivas in general who are qualifed enough for this to apply to. The word sastra applies exclusively to the Vedic scriptures and is explained etymologically as eternal and universal instructions for the benefit of all creation. This includes the four Vedas, Vedanta Sutra, Srimad Bhagavatam, the Puranas, the Upanisads, the Itithasas along with their auxiliaries and Mahabharata, Ramayana, Sri Caitanya Caritamrita, etc. which are all under the pantheon of the Vedic scriptures

The injunctions of the Vedic scriptures are in the form of: One should perform this. The prohibitions of the Vedic scriptures is in the form of: One should not perform that. An example of an injunction is that: One should perform ahimsa which is not causing harm to any living being by thought, word or action. An example of a prohibition is that: One should not eat grains on Ekadasi the 11th day of the waxing and waning moon. An example of an injunction and a prohibition is that: Cows are inviolable and should never be killed. The inference of the word should is derived from the usage of the verb in the potential mood.
